This invention relates to heel-seat fitting machines and is illustrated herein as embodied in a power-operated machine adapted to perform the heeleeat fitting operation upon shoes which are to receive wood heels of any of the types now in general use.

In the manufacture of slices having' wood heels, it is usual,.after a sole vhas been attached to shoe by stitching extending from one end of the. heel breastj line forwardly around the toe of the shoe and back on the other sider oftheshoe to the other end of the heel breast line, to trim the surplus material from the periphery of the heel-seat portion of the sole, at the same time beveling the sole to conform to the concave attachinfr surface of a woodheel, and forming a transversely extending heel breast receiving abutment in the sole at its heel breast line.` In the case of shoes to which Cuban heels. or other heels having Vsubstantially straight breasts, areto be attached, this abutment usually takes the form of twoseparate shoulders cut in the sole at opposite ends of the heelV breast line andv spaced apart by the uncut median portion of the sole. These shoulders' areinclined transversely relatively to the median Vline of the ,sole to conform' tojthe transverse curvature of the breast of a Cuban heel. A, method often used in formingthe abutment to receive the forwardly projecting portion of the breast of a Louis heel isto forni a flap in the sole by a cut extending transversely across the sole from oneedge to-thecther and inclined only slightly relatively to the tread surface of the sole, the flap thus having a relatively thick base at or just forward of the heel breast line and tapering rearwardly to a thin edge which overlies the 'breast of the heel. Y Y

Machines have been in operation` in this country for some years adapted to trim surplus material from and to bevel the periphery of the heel-seat portions of slices to prepare 'the shoes for theV attachment of wood heels and to form the transversely extending flap just referred to which is frequently used as an abutment in shoes to which Louis heels are to be attached. A. machine of this character which has gone into extensive use is 1928. Serial No. 287,430.

Vto which any type of wood heels are to be attached.

A feat-ure of the invention comprises the combinationin a heel-seat fitting machine of a cutter movable transversely across the sole of a shoe at the heel breast line of the sole to form a heel breast receiving abutment in the sole and means for moving the cutter heightwise of the shoe to vary the depth to -iwhich the cutter operates on the sole of the shoe. Preferably and as illustrated, thev cutter, as itenters the edge of the sole, cuts through the wholel thickness of the sole but is moved heightwise of the shoe so that it passes out of the sole before it reaches the vmedia-n line of the shoe. Then, after the cutter has passed the median line of the shoe, it enters the tread surface of the sole,finally cutting through the entire thickness of the sole before the other edge of the sole is reached. This cutter, moreover, in order to adapt it for work upon shoes to which Cuban heels are to be attached, is arranged, in accordance with still another feature of the invention, to enter and to leave the sole 1n a i path inclined relatively to the median line of the sole so that the abutment formed by the cutter will correspondin shape to the transverse curvature of the breast of a Cuban heel. In theillustrated machine the cutter is carried by a shaft extending heightwise of the shoe to be operated upon and positioned forwardly of the heel breast line of the sole oi the shoe. The cutteris attached to an arm projecting from the shaft and, as the shaft is rocked, sweeps across the sole of the shoe in a curved path to form a heel breast receving abutment at the breast line of the so e.

In accordance with a further feature of the invention, and to render the machine applicable to all kinds of heel-seat ittin work, the illustrated machine is provide with two abutment forming cutters alternatively operable, one to form a heel breast receiving abutment in the form of a pair of separate shoulders inclined relatively to the tread surface of thc sole only sufficiently to aline them vertically with the breast of a Cuban heel and the other of which is inclined at a small angle to the tread surface of the sole of the shoe operated upon so as to form a tapered flap for the reception of the breast of a Louis heel.

The heel-seat fitting machines which have been used rior to my invention have substantially increased the output of the operator as compared to the performance of the o eration manually. Nevertheless, these mac t'nes have been relatively slow since in the best of them the movement of the trimming cutter peripherally of the heel-seat of the sole of a shoe was manual. It is another Object of the present invention to speed up the o ration and this is done in thc illustrate machine, in accordance with a feature of the invention, by moving the trimming cutter which removes surplus material from and bevels the heel-seat portion of the sole of a shoe, as well as the cutter which forms the heel breast receiving abutment, by power. This is effective both to relieve the operator of the labor of forcing these cutters through the relatively hard and tough leather of the sole ofthe shoe operated uponand,

as stated above, to speed up the operation.

In accordance with a further feature of the invention, the cutter which trims the surplus material from the periphery of the heelseat portion of the sole. is guided in a. ath extending peripherally of the heel-seat y a guide, illustrated as a groove formed in and parallel to the edge of crease plates which enter the rand crease of the shoe to be operated upon. In the illustrated machine, this cutter takes the form of a drag-knife having a cutting edge inclined relatively to the top of the crease plates and to the tread surface of the sole of the shoe.

` A further feature of the invent-ion comprises an improved combination of a holddown member or members and a cutter or cutters whereby displacement of the heel-seat portion of the sole of a shoe by the cutter or cutters is avoided. This overcomes one of thefprincipal di'liculties heretofore met with in attempting to perform the heel-seat fitting operation by machine on welt or McKay shoes the heel-seat portions of which are not ordinarily attached with any degree of security prior to the performance of the heelseat fitting operation. The provision of this holddown member or members does not in any way interfere with the operation of the machine upon turn shoes having sewed heelseats and, indeed, is of some assistance even under those circumstances since the shoe is held more firmly than it otherwise would bc.

Some wood heels are made unsymmetrical, extending further forward on the outer edge than upon the inner edge. That is to say, the heel breast line, considered as a whole, is inclined forwardly toward the right on the heel of a right shoe and toward the left on the heel of a left shoe. It is, accordingly, a further object of the invention to provide 8 means for so positioning a shoe to be operated upon by the machine that the trimming operation may be extended somewhat further forward on the right side of a right shoe and on the left side of a left shoe than on the left side of a right shoe and on the right side of a left shoe. The illustrated machine is provided with a pair of side gages movable widthwise of the shoe, both in the same direction, to vary the transverse position of the" shoe in the machine relatively to the path of movement of the trimming cutter and the abutment-formingy cutters according as the slloe to be operated upon is a right or a left s oe.

In this specification and claims the words Cuban heel are to be taken as designating any heel having a straight or substantially straight breast, in contra-distinction to Louis heels, rather than as applicable only to Cuban heels in the strict sense of the term. They are to be taken as covering not only Cuban heels in the strict sense but also other heels of that general nature, low flat heels having substantially straight breasts, and even semi-Louis 1 heels the breasts of which are curved to a considerable extent but which lack the forwardly projecting overha-nging portion characteristic of full Louis heels.

With the above and other objects and fea- 1 tures in View, the invention will now be described with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and pointed out in the claims. l

and Y n Y o Fig. 13 is a view of the heel-seat portion of the shoe of Fig. 12 after the vcompletion of the heel-seat litting operation by the machine.

The illustrated heel-seat fitting machine is provided with a column 16', the major portion ot which is broken away in the drawings, at the top of which is carried a stationaryiead 1S provided with a horizontal table 2O having toward its right-hand side forwardly and rearwardly extending ways 22 (Fig. 6) in which a movable head (Figs. 1,2 and 6) is mounted for forward and rearward sliding adjustment, carrying with it the means tor forming heelbreast receiving abutments in the soles of shoes presented to the machine. A stationary bracket 26 extends upwardly from the table 2O to the rear of the movable head 24: and is provided with -a threaded opening receiving a screw 8G tor adjusting the movable head Q4. The head ot the screw 30 is provided with a hand wheel 32 and a dial portion 34 (Fids. 6 and 8). y

The screw 30 has a bearing arranged axially in alarger screw 86 threaded, as shown at into the movable head 2st. The dial 34 of the screw 30 and a collar 40 pinned to the screw 30 at the rear end of the screw 36 serve to prevent relative axial movement 'et the screws 30 and 36. At its head end the larger screw is provided with a hand wheel and dial 42, the dials 34 and l2 cti-operating with an index linger 44 carried by the movable head 2f-l adjacent to the dials. rlhe index linger ed may be graduated, 1i' desired, to

indicate the longitudinal as well as the rotary adjustment of the two dials; A bushing L16 surrounds the forward unthreaded portion et the screw 36 and is restrained against lon 0 4uthnal movement relatively to the screw l by tne dial l2 and a collar 4S secured to the screw 86. Y

A. spring-pressed slunger 5() (Fig. S) housed in a bore' formed in the movable head 2e passes through a slot 52 in the bushing i6 and has a conical end normally engaging one or another o/a plurality ot vshallow grooves Jormed in the non-threaded surface of the screw 36, thustendingT imp-ositively to restrain the screw 36 against Arotation and being effective to prevent rotation of the screw 36 when the hand wheel 32 and the' screw 30 are rotated. A' collar 56 secured tov the rear end of the screw 30 limits the movement ot' that screw in a forward d1- rection by 'engagementfwith the bracket Qd whiley the collar l0 limits the movement oi the screw rearwardly in a similar fashion.

Thus it will be seen that when the hand wheel 32 is rotated .the screw 30, because ot its threaded engagement with the bracket 26.

is effectiveto slide the movable head 24 forwardly or rearwardlyA the case may 'be relatively to the plate 20, the screw 36 moving lengthwise with the screw 3() but not rotering.

threaded portion yoi the srew 30 but does not-move axially, sliding` the movablev head Qdi forwardly or rearwardly by reason of its threaded engagement therewith.

As already stated, the movable head Q4 in4 the illustrated machine Vis provided with means for forming heel breast receiving abutments in the soles ot shoes operated upon On the other hand, when the dial l2 is rotated, the screw 86 turns on the non' and the position of the abutment lengthwise of the shoe is determined by the position et they movable head 24. The graduations et the dial 84 are such that rotationy of the dial the distance between two graduations slides the movable head 24 an amount equal to the difference in lengt-h between one size of heel and the next adjacent size of the same stvle ot heel, regardless ot what that particular' style maybe. The dial 4t2. on the other hand.

is used to adjust thelmovable head 24. to com-A yPensate for variations in the length of the heels of different styles but ot the same nominal size. rlhus the head 24 will be moved further forward when operatingupon a shoe to which a Louis heel is to be attached than is utilized to trim surplus material from and to bevel the periphery of the heel-seat portion of the sole of a shoe presented to the machine.

The left-hand forward portion of the plate 20 is reressed and provided with a seat 60 (Fig. 1) in the form of an arc illustrated as of about 270 degrees and arranged to receive a pair of crease plates 62, 64 (but shown in Figs. 1, 5 and 6) having a corresponding outline and arranged for arcuate adjustment about the center of the seat 60. The inner edges of these crease plates have an approximately horseshoe-shaped form and are reduced, as shown at 68 (Fig. 5), to enter the rand crease of a shoe presented to the machine. Each' crease plate is provided, parallel to its edges 68, with a groove 70, the vertical walls of which form a guide for a pair of rolls 72 (Figs. 5 and 6) depending from the lower surface of a cutter carrier 74 to which is also secured a knife 76 arranged for movement, under the control of the guide groove 70, peripherally of the heel-seat por- 'tionof the sole of a shoe the rand crease of which is engaged by the edges 68 of the crease lplates 62, 64 to trim surplus material from 'and to bevel the peripher `t0 hold a shoe which is to be operated upon is a work support 80 terminating in a last pin 82 (Figs. 2 and 9) mounted in a slide 84 for transverse movement relatively to the upper end of a tubular outer member 86 of the work support 80. The tube 86 is telesco ically mounted on a rod 90 pivoted at 92 igs. 2 and 4) to a bracket 94 attached to the head 18 of the machine. A spring 91 (Fig. 2), housed within the tube 86 and bearing at its lower end against the upper end of the rod 90, tends to raise the tube 86 of the work support 80, and the shoe carried thereby, relative movement of the rod 90 and the tube 86 4being limited by a pin 93 at the lower end of the tube 86 and engagin a slot 95 formed in the rod 90, as shown in ig. 2. Also pivoted at 92 to the bracket 94 is a pair of cams 96 the upper edges of which are engaged by a pair of rolls 98 carried by the lower end of the tube 86 (Figs. 1, 4 and 9).

It will be seen that rearward or clockwise movement of the cams 96, as viewed in Fig. 4, is eective to raise the work support 80. A rearwardly extending link 100 is pivoted at 102 to the cams 96 (Figs. 4 and 9) and is provided at its rear end with a slot 104 through which vpasses a pin 106 carried by the lower end of the depending arm of a three-armed lever 108. The lever 108 has a forwardly extending arm provided with a hand grip 110 by means of which the lever can be rocked about its fulcrum 112. A pawl 114 carried by the lever 108 and manipulated by a supplemental lever 116 fulcrumed to the rear end of the hand grip 110 co-operates with a ratchet 118 fast to the frame 18 of the machine to hold the lever 108 in adjusted position. A spring 120, fast at one end to the pin 106 and at the other end to an adjustable screw 122 carried by the forward end of the link 100, forms an operative connection between the lever 108 and the cams 96 so that downward movement of the hand grip 110 serves impositively to rotate the cams 96 in a direction to raise the work support 80 and a shoe mounted upon a last carried thereby, while upward movement of the hand grip 110 serves positively to rotatethe cams 96 in the `opposite direction, to permit the work support to be lowered. As this vis done, the operator moves the work su port 80 forwardly removing the shoe from tlie crease plates 62, 64, and this he can do without diiculty by reason of the presence of the spring 120 and the pin and slot connection 104, 106.

The detail of construction of this work supporting mechanism is not claimed in this application since it forms the subject-matter of my co-pending application Serial No. 17 0,881, yfiled February 25, 1927, for improvements in Heel-seat fitting machines.

The position of the crease plates 62, 64 in the seat is adjusted by movement of the lever 108 (Figs. 4 and 9) since that lever is provided with an upwardly extending arm 130, the upper end of which is pivoted at 132 to a horizontal, transversely extending lever 134 fulcrumed at 136 to the plate 20, as shown in dotted lines in Fig. 6. The median portion of the lever 134 is connected by a pair of links 138 with the crease plates 62 so that downward movement of the hand grip 110 moves the forward portions of the crease plates 62, 64 toward each other. narrowing the spread of the horseshoe-shaped rand crease entering edges 68 of the crease plates.

The upper end of the movable head 24 is provided with an arm 140 extending to the left, as shown in Figs. 1 and 2, and provided near its end with a vertical slideway 142 in which is mounted a slide 144 normally held in elevated position by a bell crank lever 146 fulcrumed at 148 to the movable head 24 and urged in a clockwise direction, as viewed in Fig. 2, by a spring 152 secured at one end to the depending arm of the bell crank lever 146 and at the other end to the arm 140. A pin 154, proiecting forwardly from the slide 144, is positioned above and engages the ap-4 proximately horizontally extending arm of the bell crank lever 146. A stop screw 156 is adjustably carried by the slide 144 and engages a shoulder 158 carried at the rear of the arm 140 to limit downward movement of the slide 142 under the influence of mechanism which will now be described.

A treadle 160 (Fig. 4) yis fulcrumed at 162 l will do no damage.

near the base of the column 16 and is connected by a rod 164 with a lever-166' fulcrumed at 168 to the bracket 26 and extending toward the left, as best shown in Figs. 1 and 2. Mounted for sliding movement lengthwise of the lever 166 is a rod 170 urged toward the left by a spring 172 securedA at one end to the rod 170 'and' at the other end to the lever 166. When the rod17 0 is moved to the leftv by the spring 172, its left-hand end is positioned abovel a roll 174 carried by a pin 17 6 extending rearwardly from the slide 144, as shown in Figs. v1 and 2. With the parts in this position, it will be seen that depression of the treadle 160 is effective to rock the lever 166 in a clockwise direction, thus forcing the slide 144 downwardly until the lower end of the screw 156 engages the shoulder 158 of the arm 4140.

Mounted for vertical sliding movement in ways formed at the rear of the left-hand end of the arm 140 is a holddown member 180 (Fig. 2) in the upper portion of which is formed a sleeve v182 surrounding a rod 184 attached by a link 186 to the left-hand end of the lever 166, as shown at 188. A spring 189 is housed within the sleeve 182 andL provides a yieldable connection between the sleeve 182 and thev rod 184 so thaty when the central part of the heel-seat portion of a shoe carried by the work support and the rand crease of which has been entered by the crease plate 62 is engaged by the holddown member 180, further downward movement of the left-hand end of the lever 166 Carried at the lower end of the slide 142 are a pair of springpressed holddown members 190 arranged to engage the sole of the shoe just forward of the ends of its heel breast line. These three Y holddown members are effective to prevent the displacement of the heel-seat portion of the sole of a shoe while the heel-seat fitting operation is being performed, even though the sole attaching means does not extend rearwardly of the heel breast line, as is commonly the case in the manufacture of McKay and Goodyear welt shoes and in the manufacture of some turned shoes.

A vertical. rcclr shaft 200 is journaled in the i slide 144 and is provided at its lower end with an arm 202 to which is secured a cutter v204 illustrated as a knife havingl a channelshaped cutting edge (Fig. 2). The shaft 200 is positioned about two inches forwardly of the heel breast line of ythe sole of a shoe to be operated upon so that as the shaft 200 is rocked the knife 204 will be moved transverse- Vly across the sole of a shoe positioned in the machine, at the heel breast line of the sole, so that the forward, approximately vertical, cutting edge of the knife 204 willcut a heel breast receiving abutment in the sole while the horizontal portion of the cutting edge and the upturned portion at the rear will sever y a chip from the sole leaving a groove in the sole g of an inch more or less wide. In order that the abutment may consist of two portions separated by the uncut median portion of the sole, is commonly desired in performing the heel-seat fitting' operation upon shoes to which Cuban heels are to be attached, a cam 210 (Figs. 1 and is carried by the sli-de 144 and a cam roll 212 lcarried by an arm 214 pinned to the shaft 260 is held in engagement with the Vcam 210 by a spring 216 surrounding the shaft 200 and bearing at its upper end against an abutment 218 carried by the slide 144 and at its lower end against a collar 220 secured to the'shaft 200. The cam 210 is of such a formation that the cutter 204, when it enters the sole at the right, cuts through the entire thickness of the sole but-V of the sole, cuts through the entire thickness of the sole', thus providing an abutment of the character shown at 224 in the solo 226 of the shoe 228 illustrated in Figs. 12 and 1 3., which abutment, it will be noticed, is formed in two separate portions each of which is inclined relatively to the median line of the shoe to correspond with the transverse cur,- vature of the 'breast of a Cuban heel.

Y When the slide 144 and the holddoWn member 180 are moved downwardly by the 1de,- pression of the treadle 160, they are held in that position by reason Vof the fact that the treadle 160 is latched in depressed position by the engagement of a dog 230 (Fig. 4), fulcruined at 232 to the treadle 160, beneath a latch plate 234 carried by ,the column 16 of the machine and the parts are held latched in this way until after the heel breast receiving abutment has been cut,

rhe shaft 200 is provided with a pinion Or gear segment 285 engaging a rack bar 236 mounted for horizontal movement in the slide 144, the left-hand end of the bar 236 contasting with a depending lever 238 Afulcrumed at 240 to the top of the slide 144 and urged in Va oounterclochwise direction, as viewed in Figs. 1 and 2, by a spring 242 secured at one end tothe lever 288 yand at the other .end to the slide 144. Thus it will be seen that movement of the rack bar 236 to the left is effective to operate the 1imife 204 to form a heel breast receiving abutment in the sole of a shoe presented to the machine while the knife 204 willV be returned to its normal position at the conclusion of the operation byA type. The clutch 250 has a continuously rotated member 251 (Figs. 4 and 6) splined on a shaft 253 driven from a shaft 255 by spiral gears 257. The shaft 255 carries a worm disk 254 is provided with a crank pin 256 (F 2) to which is pivoted aconnecting rod 258 extending to the left and terminating in a. horizontal forwardly extending pin 260 normally positioned at the left-hand end of a slot 262 formed in a slide bar 264 mounted for transverse movement to the left in a ideway formed in the movable head 24.

e pin 260 isof such a length that the operation of the bar 256 is in no way interfered with by forward and rearward adjustment of the movable head 24. At its forward end the slide bar 264 is provided with an upwardly extending plate 266 which, while the machine is at rest and the slide 144 is in its lowered position, is in horizontal alinement with and closely adjacent to the right-hand end of the rack bar 236. Thus depression of the hand lever 252 is effective to move the rack bar 236 to the left and to cause the cutter 204 to form the heel breast receiving abutment in the sole of a shoe. A spring 280, secured at its right-hand end to a pin 282 carried by an extension of the connecting' rod 258 and at its left-hand end to the slide bar 264, is effective to return the slide bar to the position shown in Figs. 1 and 2 at the conclusion of the operation.

After the heel breast receivingr abutment has been formed but before the surplus material has been trimmed from the periphery of the heel-seat portion of the sole of a shoe, the slide 144 is raised to the position shown in Fi 2, the holddown member 180, however, ing maintained in engagement with the sole of the shoe. This is permitted by longitudinal movement of the rod 170 while the lever 166 is maintained latched in its depressed position by the dog 230. For this purpose a lever 290 is fulcrumed at 292 to the movable head 24 with its upper end extending somewhat above and to the left of a forwardl projecting finger 294 carried at the rightand end of the rod 170. A springpressed latch 296 (Fig. 3), housed in the lever 166 near its fulcrum is arranged for engagement with a shoulder 298 formed in the rod 170 so that when the lever 290 1s rocked through a small angle in a clockwise direction, as viewed in Figs. 1 and 2, the rod 170 will be moved to the right and latched in that position by the latch 296. This movement of the rod 170 to the right causes ythe left-hand end of the rod to pass out of engagement with the roll 174 of the slide 144 So that the latter can move upwardly which it does under force applied by the spring 152.

The latch member 296 is slidably mounted in a sleeve 297 carried by the lever 166. A spring 299, bearin at one end against a block 301 screwed into t e sleeve and at the other end against the latch member 296, tends to move the latter forwardly while another spring 303, surrounding the sleeve and bearing at one end against a collar 305 formed on the rear of the sleeve 297 and at the other end against a shoulder 307 formed in the lever 166 and surrounding the sleeve 297, tends to move the sleeve 297 rearwardly.V The collar 305 at the rear of the sleeve 297 is provided with a beveled surface 309 arranged, when the lever 166 is rocked in a counterclockwise direction from the position in Fig. 2, to engage an inclined surface 311 formed on the bracket 26 so that the sleeve 297 is thrust forwardly bringing the latch member 296 into operative position so that it may be eiectiveto engage the rod 170 when the latter is moved to the right to bring its shoulder 298 into alinement with the latch member 296. On the other hand, when the lever 166 is swung upwardly to the position shown in Fig. 2, the s rin 303 will move the collar 305 rearwar ly wlthdrawing the latch member 296 and rendering it inoperative. A projection 313 formed on the sleeve 297 engages a fiat surface 315 at the front end of the latch member 296, limiting forward movement of the latch member in the sleeve 297.

In order to rock the lever 290, its median portion is connected by a link 300 with a dependin lever 302 the upper end of which is provi ed with a slot 304 through which passes a fulcrum pin 306 carried b the movable head 24. The lower end o the lever 302 engages the upper surface of the slide bar 264 in which surface is provided a notch 308 which the lower end of the lever 302 enters when the slide bar 264 moves to the left so that, as the slide bar 264 is returned toward the ri ht, the lever 302 is rocked through a sma 1 angle in a counterclockwise direction (as viewed in Figs. 1 and 3) thus rockin the lever 290 in a clockwise direction and wlthdrawing the rod 170 from the roll 174. rl`he rod 170 is latched in this withdrawn position by the latch 296. Before the slide )ar 264 has reached its normal inoperative position, as shown in Fig. 2, the rotation of the lever 302 lifts the lower end of that lever out of the notch 308 and a spring 310, anchored at one end to the movable head 24 and at the other end to the lever 302, returns the lever to substantially the position shown in F ig. 2.

If, instead of fitting the shoe to be operated upon for the reception of a Cuban heel,

l provided with af handle 322 by which it it is desiredto tit the shoe for a Louis heel by cutting from the sole a tapered iiap beneath which the forwardly projecting portion oi the heel breast may be positioned, the operation oi the machine is somewhat diiierent. When the machine is to be operated in this manner, the lever 290 is rocked a few degree. in a clockwise direction, as viewed in Figs. 1 and v2, bythe rotation through 180 degrees of a manually adjustable cam or eccentric 320 "1""7' be moved. This moves the rod to the rr,

and holds it in that position. Prelims-ment ot' the eccentric320 is also effective to rock, in aclockwise direction, a lever 324 also tulcrume'd at 292 to the movable head 24 and urged I in a counterclockwise direction, as viewed in Figs. 1 and 2, by a spring Below 'its ulcrum the lever 324is provided with a slot engaging a` pin 328 carried by an upwardly extending arm ot a bell crank lever '330 provided also with a horizontally eX- tending arm from which alinger 332 extends forwardly into a notch 334 formed in the upper endet a plunger 336 mounted for endwise sliding movement in alever 338 loose upon the shaft 340 to which is pinned a rock arm 342 having in its upper end a Vnotch termed to receive the lower end ot the plunger-336 when the latter is depressed by clockwise movementor'a the lever 330. The lever 338 is normally held in engagement with a pin by a spring 345 (Fig. 1). rEhe latch mechanism, indicated at 344, which may comprise a spring-pressed ball arranged to enter one of two depressions formed in the plunger 336.y serves impositively to hold the plunger 336'eitlier in its elevated, inoperative position, shown in Figs. 1 and 2, or in ite lower position in which its lower end enters the not-ch oit the rock arm 342. Also pinned to the rock arm 342'is a second arm 346 to the end otfwhi'ch is secured a. downwardly extending link 348 connected tothe treadle rod 164 (Fig. 2).. '-Thus, it' the eccentric 320 is rocked degrees Jfrom the position shown in F ipfs. 1 and 2, {depression/ot' the treadle 160 will be effective to Arock the' lever 338 in a 'counterclockwise direction, as viewed in 1 an( 2.v The upper end ot the lever 338 is connected hy a link 350 to lever 352 tulcrumed to the movable head2-l of the machine and provided its upper-end with a pin 354 1, 4 and 6) ext-ending beyond the end or' the slide bar 264 and closely adjacent theret5, sov as to move the slide bar to the left when the lever 052 is rocked. YWhen this takes place, the right-hand end of the slot 262 moves into engagement with the pin 260 oi: the connecting rod 258 and the pin 260 drops into depending portion 356 Vwith which the right-'hand end 'of the slot 2.62 is provided. l/Vchenoperating the machine in this manner it not desired tol utilize the holddown 'members 180, v190 nor the cutter 204. Accord` ingly, a supplemental treadle 3601 is fulcrumed at 362 to the treadle 160, the treadle 360 carrying at its rear end a. cam roll 364 engaging a cam surface with which the dog 230 is provided, the arrangementk being such that depression of the treadle- 360 relatively to the treadle 160 rocks the dog 230 out of engagement with the plate 234 against the tension of a. spring 366 secured at one end to the dog 230 and at the other end to the treadlc 166, normally te ding to urge the dog 230 into engagement with the plate 234. lt the foot is placed upon the supplement treadle 360 as well as the treadle 160 when the latter is depressed to move the slide bar 264 so as to bring the pin 260 into the depending portion 356 of the slot 262, then when the foot is removed the lever 166 will move upwardly to the position shown in Figs. 1 and 2, removing the holddown members 180 from the heel-seat portion of the sole of the shoe. T he slide 144, which carries the cutter 204 d and the holddown members 190 will not have been lowered since the rod 170 was held by the lever 290 too far to the right to engage with the roll 174.

lThe slide bar 264 serves also as a carrier for a knife or cutter 370, best shown in Fie'. 2, having a straight cutting edge an inca or more wide and extending lengthwise of the shoe but somewhat inclined relatively to the tread surface of the sole of the shoe, as more fully disclosed in Letters Patent oi the United States No. 1,661,391, granted March 6, 1928, on an application of Tilliam C. Stewart. This knife is preceded by a holddown in the form of a roll 372 also of the character disclosed in said-Letters Patent. lrlovement of the knife 370 transversely across the sole of a shoe presented to the nia*- chine, from one edge of the sole to the other at its heel breast line, will form in the sole a. flap the rear end ot' which is thin but the forward portion ot which, at or slightly forward of the heel breast line, is thicker. the flap being of the character shown in Letters Patent of the United States No. 1.527.963. granted February 24, 1925, o-n an application iiled in the name of John L. Preo and Isabelle 'Henne yThe forwardly projecting portion of the breast of a Louis heel may be positioned beneath this Hap, as also disclosed in said Letters Patent.

It thehand lever 252 is depressed while the parts are in the condition just described with the pin 250 engaging a downwardly project-ing portion 356 of the slot 262, the rotation of the crank disk 254 is edective to move the slide bar 264 in such a manner that the knife 370 carried thereby will move transversely across the sole of the shoe, from one edge-to the other, cutting in the sole a flap of the character described. During the first halt of the return stroke of the crank disk 254, however, the connecting rod 258 strikesthe table 20 andrits left-hand end is rocked upwardly, moving the pin 260 up out of the depressed portion of the slot 262 so. that rthe guide bar 264 will return to its extreme right-hand position, as shown in Figs. 1 and 2.

After the heel breast receiving abutment has been formed in either of the ways which have been described, the machine is operated to trim the surplus stock from and to bevel the periphery of the heel-seat portion of the sole of the shoe so that the peripheral portion of the heel-seat will be left in the condition shown in Fig. 13. For this purpose the cutter carrier 74 and the cutter 76 carried thereby are moved periphcrally of the heel-seat portion of the sole of a shoe by mechanism which will now be described.

By referringto Figs. 5 and 6, it will be seen that the left-hand forward portion of the left-hand crease plate 64 is cut away to receive a transversely slidable block 400, the right-hand end surface 402 of which, when the block is slid to its right-hand position as lshown in Fig. 6, forms a continuation of the left-hand vertical surface of the guide groove 70 of the crease plate 64. A pin404 extends upwardly from the block 400 and is received in a slot 406 at the forward end of a lever 408 fulcrumed at 410 to the table 2() and connected by a pin and slot connection 412 with a lever 414 fulcrumed at 416 to the table 20 and the rear end of which is connected by a transversely extending link 418 with a horizontally movable lever 420 (best shown in Figs. l, 6 and 9) fulcrumed at 422 (Fig. 6) near the rear of the head 18 of the machine and having pivoted to its front end at 424 (Fig. 9) for vertical swinging movement a bell crank lever 426, the forward end of which serves as a handle by which the lever 420 may be moved transversely of the machine.

When the machine is in inoperative position and While the heel breast receiving abut ment is being formed, the block 400 is positioned to the left, as shown in Fig. 5. After the heel breast receiving abutment has been formed, however, the lever 426 is moved to theleft, causing tne block 400 to move to the right to the position shown in Fig. 6, in which movement it is guided by a slideway 430 formed in the table 20 and receiving a rib projectingr from the block 400. )Vhen once it reaches this position, the block 400 is latched therein by a pivoted latch member 432 (Fig. 5) the left-hand'end of which engages a shoulder 434 carried by the table 20, the right-hand end of the latch being held in elevated position by a spring 436. The latch 432 is effective only when the cutter carrier 74 is in a position other than its lefthand forward position at which time the right-hand end of the latch member 432 is held depressed by the cutter carrier 74.

Near its right-hand end the block 400 is provided with an upwardly extending rib 438 received in a groove formed in the lower surface of the cutter carrier 7 4 so that when the cutter carrier 74 is at the left-hand end of its path of movement, it can be moved transversely of the machine with the block 400.

A latching member 440 (Figs. 1 and 2) is pivoted at 442 to the head 18 of the machine and is held upwardly by a spring 444 at its left-hand end. A lug 446, the right-,hand surface of which is inclined relatively to the body of the latch member 440 but the lefthand surface of which is vertical, projects upwardly from the latch member 440 and serves to retain the lever 426 in its left-hand position when it is moved thereto and thus holds the block 400 in its right-hand position, independently of the operation of the latch 432, until the lever 426 is moved to the right to its inoperative position. When the cutter carrier 74 is moved toward the rear, the latch 432 becomes effective and is effective to hold the block 400 in its right-hand position, as shown in Fig. 6, until the cutter carrier 74 has been moved peripherally of the heel-seat of the sole of a shoe to trim sur lus material therefrom and has been returne again to the position of Fig. 6 at which time it engages an inclined portion 450 formed at the rear of the right-hand end of the latch 432 and forces the right-hand end of the latch downwardly, thus releasing the latch so that the block 400 can be moved to the left to the position shown in Fig. 5. The utilization of the cutter carrier 74 to unlatch the block 400 prevents the movement of the block 400 to the left before the cutter carrier 74 has moved into such a position that it may be moved to the left with the block 400 and thus constitutes an effective safety device and prevents jamming and possible 1nj ury to the machine.

The cutting edge of the knife 76, indicated at 464, is inclined and may be slightly curved relatively to the plane top surface of the crease plates 62, 64. The sole of the shoe is engaged immediately in front of the knife 76 by a spring-pressed holddown member 466 (F1g. 5) carried by an arm 460 projecting from the cutter carrier 74 immediately in front of the knife 76. A pin 462 asses through a slot 468 near the front en of a rearwardly extending pitman 47() (Figs. 5 and 6) which is operative to move the cutter carrier 74 peripherally of the heel seat of the shoe. A short slide block 472 positioned in the slot 468 receives the pin 462 and together with the pin is urged rearwardly by a spring 474 connected at one end to the slide block 472 and at the other end to the ptman 470. This construction is effective to prevent jamming of the cutter carrier 74 in the guide groove as the cutter carrier is moved about the rear portion of the guide 70 under the .scribe-vd.` g w gear 500 (Figs. 6 and 9) meshing with a spi- Vbe driven in either direction.

variousY positions of adjustment which the crease plates take when the machine is opereccentric, the rear portion of the pitman, and

adjacent parts of the machine, projects into a hole 492 in the pitman (Fig. 6). The rear portion of this hole 492 is of such a size that the pin 488 clears its walls at all times. The forward portion 494 of the hole 492 engages the pin 488 as the cutter carrier 74 moves about the i'ear of the shoe, guided by the rear portion ofthe guide groove 70, and serves as a fulcrum about which the pitman 470 swings at that time..

The eccentric 482 is driven from the motor 268 bv mechanism which will now be de- Fast on the shaft 255 is a spiral ral gear 502 of a reversible transmission gearing contained in the gear casing 486 through which passes the shaft 484 of the eccentric 482. Formed integrally with the spiral gear 502 is a bevel gear 506', these gears, which are continuously driven, being loose upon the shaft 484 but restrained against movement lengthwise of the shaft. Meshing with the bevel gear 506 is a bevel gear 508 mounted on a stub shaft 510 carried by the transmission gear casing 486 and meshing also with a bevel gear 512 loose upon the shaft 484. The lower bearing 514 for the shaft 484 extends downwardly from the bottom of the gear casing .486. asshown in Fig. 9, a ycollar 516 being fast upon the shaft 484 below the bearing 514. Tending to rotate the shaft 484 and the eccentric 482 in a clockwise direction, as viewed in Figs. 6 and 10, is a spring 518 (Fig. 9) secured atone end to the collar 516 and at the other to the bearing 514. Splined to the shaft 484 between the bevel gears 506 and 508 is asleeve 520 having a dogf522 projecting from each end thereof, the dogs being arranged, whenthe sleeve is slid one Way or the other, to engage cooperating slots 524 formed in the hubs of the bevel gears 506, 512, Thus, by sliding the sleeve 520 in one direction or the other, the eccentric 482 may Vhen the sleeve 52() is inits intermediate position, the gearing' is in neutral and the shaft 484 and the eccentric 482 remain at rest.

to lower the sleeve 520. thereby causing the gear 512 to rotate the shaft 484 and the eccentric 482 in a counterclockwise direction,

as viewed in Fig. 6.\ This moves the cutter carrier 74, which at this time is in the posiv Depression of the hand lever 426 iseffecy tion shown in Fig. 6, and the cutter 76 pe- .ripherally of the heel-seat of the sole of the shoe to be operated upon, trimming surplus material from and beveling the peripheryof the heel-seat, the cutter carrier 74 coming to rest at the right-hand end of the groove 70. The connections between the lever 426 and the sleeve 520 include a link 529 (Fig. 9) pivoted at 536 to the upwardly extending arm of the bell crank lever 426 and at 532 to the upwardly extending arm of another bell crank lever 584 fulcrumed at 536 inside the' gear casing 486 and having a rearwardly extending arm 538 provided with a slot near its end in which is located a pin 54() (Fig. 11) arranged at the rear of a lever'542 fulcrumed in the gear'casing 486 and having at its forward end a yoke 544 pivoted to a U-shaped member 546 positioned in a groove in the sleeve 520. A compression spring 550', bearing at one end against the lever 542 between its fulcrum and the pin l540 and at the other end against a stationary part, tends to rock thev lever 542 inl a clockwise direction, as viewed in Fig. 11, and to lift the sleeve 520 to its neutral position. The link 529 isillustrated as made up of two yi eldingly connected parts, as shown at 531, so that the downward movement of the hand grip of the lever 426 will be somewhat cushioned and vdown-v ward movement in excess of that necessary to 4 shiftthe transmission gearing will be harmless.

Mechanism, which will now be described, is provided to throw the transmission gear-v ing into neutral when the cutter carrier 74 has completed its movement and has arrived at the right-hand end of the guide groove'70. For this purpose the eccentric 482 is provided with a lug 560 on its lower surface, thelug 56() having a pair of inclined surfaces 562, 564 arranged, when the eccentric has completed somewhat less than a single cycle of revolution in either direction and when the cutter carrier 7 4, accordingly, has reached Y one end or the other ofL its path of movement, to throw the transmission mechanism into neutral. As the forward motion of the cutter carrier 74 must bevaried in accordance with the length to which the heel-seat ofa the transmission gearing into neutral. For, Y this purposea pair of gear sectors 570, 572 (Figs. 6 and 10) are pivoted at 574, 576 yto the table 2O beneath the cover plate 490, meshing with each other forwardly of the shaft 484. The gearsector 570 is connected by a link 58() with an arm 582 adjustablysecured to and movable with the movable head 24. Thus the position of the gear sectors 570, 572 is dependent upon the ,position of the movable head 24. As the latter'is moved forwardly l ioo to the machine to operate upon a shoe to which a longer heel is to be attached, the rear portion of the gear sectors 570, 572 move toward each other and forwardly. Each of these gear sectors is bored at its rear portion to house a plunger 586 (Figs. 9, 10 and 11) at the upper end of which is arcap 588, having a conlcal upper end arranged for engagement .with one or the other of the surfaces 562, 564`of the lug 560 as the eccentric reaches the end of its revolution. The lower ends ofthe plungers 586 are positioned adjacent to a dffver the ends of a two-armed lever 590 flcrumi.' `ed ,at 592 (Figs. 10 and 11) to the garvc'asing 486 and connected by a link 594 with the lever 542. When the eccentric 482 reaches the end of its revolution in acounterclockwise direction, as viewed in Fig. 10, the ISurface 564 will engage the cap 588 at the upper Aend of the plunger 586 carried by the gear sector 572 so that the plunger will be deressed, rocking the lever 590 a few degrees 1n a clockwise direction, as viewed in Fig. 11,

raising the U-shaped member 546 and the 25 leev'ev 520 and throwing the transmission ring into neutral. At this time the heel-- seat fitting operation will have been finished. `The hand lever 426 will next be raised, as 'more fully hereinafter described, raising the sleeve 520 and causing the transmission gearing to rotate the eccentric 482 in a clockwise direction, as viewed in Fig. 6, thus returning the cutter carrier 74 to the left-hand end of the guide groove 70. When the cutter carrier 7,4 reaches this position, the surface 562 of the lug 560 will engage the cap 588 of the plunger 586ecarried by the gear sector 570 and the transmission gearing will again be thrown into neutral so that the cutter carrier 74 will come to rest. Adjustment of the movable head2/4 forwardly will permit the eccentric 482 moreV nearly to complete a single cycle of revolution while adjustment of the movable head 24 rearwardly willhave the opposite eet. As the movable, head 24 is adjusted forwardly,the spring 518 causes the eccentric A82 to revolve, maintaining the guide surface 564 in engagement'with the cap 588 of the plunger 586 carried by the gear sector 570.

In order to facilitate the operation of the machine, the hand lever 110 is provided with an arm 600 arranged, as the hand lever 110 is moved upwardly to release a shoe at the conclusi'on of the operation, to strike. the lever 426, thereby moving/che forwardy end of the latter upwardly to cause the transmission @carin to effect the return movement of the eccentric 482 and the cutter carrier 74. Thus,

`it, is not necessary for lthe operator to raise fthe lever 426 as a separate step in the operation of the machine. n

,y ,The upward movement of the lever 110, moreover, is utilized to release th-e treadle dog 230 from the latch plate 234, lthereby permitting the lever 160 to be elevated by a s ring 602 with which it is provided so that tie lever 166 may move upwardly, 'permitting the holddown 180 to be elevated at Ithe conclusion of the operation upon a shoe to which a Cuban heel is to be attached without f'. yfurther `attention on the part of the operator. For this purpose the lever 110 is connected by a rod 604 (Fig. 4) with a rearwardly extending arm 606 connected to the dog 230, the arrangement being such that elevatlon of 4the lever 110 rocks the dog 230 in a clockwise direction, as viewed in Fig. 4. The rod 604 is provided with a connection 608 permitting lost motion so that it does not interfere with the release. of the dog 230 by the supplemental treadle 360 when it is desired to operate the machine in that manner.

It will be remembered that the levers 420 and 426 are latched in their left-hand position, as illustrated in Fig. 1, while the trimming operation is being performed. Mechanism, which will now be described, is provided for unlatching this lever and returning it to its right-hand position at the conclusion of the operation. For this purpose the lefthand end of the latch 440 is provided with a pin 612 positioned in a slot 614 formed at the upper end of a rod 616 the lower end of which is connected to a lever 618 (Figs. 1, 4

and 9) fulcrumed at 92 to the bracket 94 and rigidly secured to the cams 96 so that. when the latter are moved forwardly as a result of the raising of the lever 110, the latch 440 will be depressed, thus withdrawing the shoulder 446 from the lever 420 and permitting that.

lever to be moved to the right by a spring 620 provided for that purpose and correspondingly to move the block 400 t0 the left to the position shown in Fig. 5. j

Gage mechanism, which may be used to position the shoe carried by the work support and the rand crease of which is engaged b v the edges -68 of the crease plates 62, 64,'is illustrated particularly in Fig. 7. For this purpose a back gage 630 is carried at the forward end of a slide 632 mounted for sliding movement in ways formed in the under side of the table 20 to the rear of the Vcenter about which the crease plates 62, 64

are adjustable. A pin 634 extends downwardly from the slide 632 and is engaged by the end of a lever 636 fulerumed at 638 to the table 20 and the other end of which is pivoted to a block 640 threaded to receive the rear end of a hand screw 642 mounted for rotary movement but restrained against longitudinal movement in a plate 644 secured to the head of the machine, as best shown in Fig. Thus the `gage 630 may be adjusted manually by the` rotation of the screw 642 which is provided at its forward end with a knurled head to facilitate such adjustment.

The machine ma if desired, also be provided with a pair ofyside gages 650, 652 (Fig. 7) arranged to engage the upper of theshoe i attached.

adj arent to the solev inthe neighborhood of the-heel breast line, thereby positioning the slice -ransversely in the machine. These side gages 650, 652 are arranged for adjustment transversely of the shoe both in the same direction sothat the median line of the shoe to be operated'upon may be swung slightly out of alinement with the median line of the guide groove 70, if it is desired to extend the trimming cut a little further forward on the right side. than on the left side of a right shoe and correspondingly further forward on the left side than on the right side of a left shoe. For -this purpose vthe side gages 650, 652 are pivoted to a pair of slide members 654,656 mounted for transverse movement in ways carried by the crease plates 62, 64. The rear ends of the slide members 654, 656 engage a vpair of slidable wedges'658, 660

which in turn engage a pair of stationary but adjustablev wedges 662, 664 carried by the crease plates. The wedge 658 is connected by'a link 666 to a lever 668 fulcrumed at 670 to the crease plate 62 and provided its other end with a slot672 in which is positioned apin 674 mounted in a corresponding lever 676 fulcrumed at 678 to the crease plate 64 and connected atits other end to a link 680 pivoted to the rear end of the wedge 660. The forward end of thewedge 660 is connected by a link 682-to a manuallyY operable bell crank lever 684 fulcrumed at 686 to the head of themachine. The bell crank lever 684, when rotated in a clockwise direction, as viewed in Fig. 7, will move the wedges 660, 65S forwardly, thus moving theside gages 650, 652 to the left while, if the bell crank lever 684 is rotated in the opposite direction,

the side gages will be moved to 'the' right. lf it is not desired to use this mechanism. the lever 684 may be placed in an intermediate position; Y

lVhile the operation hasrepe'atedly Ybeen referred to in connection with the description of its construction, itfwill now bev described brieiyin connection with the performanceof the heel-seat fitting operation upon'a shoe Lto which a Cuban heel is to be The shoe to be operated upon is placed on the last pin 32 (Fig. 2), the work support at that time 'leaning forwardly from its pivot 92. The shoe is then moved rearwardly, carrying the work support with it, the'hand lever 110 at ther saine time being depressed so that the edges 68 r of ythe crease plates 62, 64 enter the .rand crease of the shoe. As this takes place thecams 96, Inoving in a clockwise direction viewed in Fig. 4, force the shoe upwardly against the lower surface of the edge portion of the crease pla-tes 62, 64, the shoe thus being securely ield andthe position ofthe crease'plates and of the guide groove vT0 being" determined by the width of the shoe.Y The position ofthe shoe longitudinally in the machine is detervmined by the back gage 630, and the side gages 650, 652 may be utilized to determine its transverse position if desired.

With the shoe thus positioned, the operator steps upon the treadle 160, thus rocking the lever 166 downwardly and moving the holddown member 180 into engagement with the heel-seat portion of the sole of a shoe, at

vthe same time causing the rod 170, which at that time projects above the roll 174 carriedv crank disk 254 and the connecting rod 258 tov move the slide bar 264 transversely of the machine and causing its plate 266 to engage the right-hand end of the rack bar 236, thus rotating the vertical rock shaft 200 and causing the cutter 204 to move transversely across the shoe at its heel breast line, forming a heel breast receiving abutment in the sole of the shoe. As the cutter 204 passes the median portion of the sole of the shoe, the shaft 200 and the cutter 204 are moved heightwise of the shoe so that the abutment formed in the shoe is made of two separate parts of the form shown in Fig. 12. The slide bar 264 is returned to the position shown in Fig. 2 by the spring 280 and the rack bar 236 and the cutter 204 are returned by the lever 238 and its spring 242. During thereturn of the guide bar 264, the shoulder 308 of the .guide bar catches the lower end of the lever 302, rocking that lever somewhat in a counterclockwise direction, and by reason of the link 300 rocking the lever 302 in a clockwise direction so that the rod 170 is moved to the right, releasing the slide 144 which is moved upwardly by the spring 152. The rod 170 is latched in position at that time by the latch 296 which engages the shoulder 298 of the rod 170.

rlhe operator now grasps the lever 426,`

time, bringing its surface 402 into alinement.

with the left-hand vertical surface ofY the left-hand end of the guide groove 7 0 so that the cutter carrier 74 may be moved peripherally of the heel-seat of the shoe under the control of the guide groove 70. This move-`V ment of the .block 400 brings the cutter 7 6 and the holddown 466 into engagement with the `shoe in the manner indicated in Fig. 12. Depression of the lever 426 is in turn effective to cause the transmission mechanism to rotate ingvedges, and a cutter constructed and arthe eccentric 482 through nearly a complete revolution, causing the cutter 76 to travel peripherally of the heel-seat and finally to come to rest, after completing the trimming operation, adjacentto the heel breast line at the other side of the shoe. The operator :then grasps the hand lever 110 and the lever 116 which controls the pawl 116, releasing `the pawl and raising the lever 110, at the same time manually moving the shoe and the work support forwardly. The upward movement of the lever 110 "causes its arm 600 to strike the lever 426,

raising that lever and thus rendering the transmlsslon mechanism ei'ectlve to rotate the eccentric 482 in the reverse direction, re-

. it the cutter carrier 7 4. Shortly before this the latch 440 has been released by the for- Ward movement of the Work support 80 so that when the latch 432 is released the block Y.400 'and the lever 426 are free to be moved to the left and to the right, respectively. The upward movement of the lever 110, moreover, is effective to release the dog 230 from the 'plate 234 so that the treadle 160 may be raised-by its spring 602 and the lever 166 is thereby moved upwardly, the latch 296 at this time being moved rearwardly by its spring 303'to release the rod 170.
